CAN-WASHNG MACEXNE.

Application led August 25, 1919. Serial No. 319,710.

To all wizom imag concern l Be it known that l, "WALTER il. PAULsoN, a citizen of the United States, and a resident of the city ot Chicago, county of Cook, and State of lllinois, have invented certain new and useful lmprovements in 'Can-Washing Machines, ot' which the following is a specitication.

My invention relates to improvements in can washing machines, and more particularly to means :tor caring "for waste water therefrom, the `obj ect of the invention being to provide a simple and eiiicient means for properly ltaking care of the waste water from can washing machines or the like.

Other objects will appear hereinafter.

"llhe invention consists in the combinations and arrangements of parts hereinafter described and claimed.

The invention will be best understood by reference to the accompanying drawings forming a part of this specilication, and in which,

Fig. l is a transverse section of a can washing machine equipped with means embodying the invention.

Fig 2 is a longitudinal section of the same.

The preferred form ot construction, as illustrated in the drawings, comprises the usual drain tank 3, adapted to receive the washing liuid employed in washing the cans in lthe usual manner. A. rinsing nozzle 3 is positioned over the tank 3 and adapted to inject a. spray of rinsing water into the inverted cans a as they pass thereover, said rinsing water being adapted to drain or dow into the tank 3. The tank 3 is provided with a valved outlet pipe 5, by means of which the contents thereof may be withdrawn for a preliminary rinsing or washing of the cans or for other purposes, and it is desirable to maintain the liquid in the tank 3 at a constant level, but not weaken the solution unduly by adding too much of the rinsing water.

To this end l place a funnel-shaped receiving vessel 6 inthe upper portion of the tank 3 immediately under the rinsing nozzle 3', said receiving vessel being provided on opposite sides with hook-like ears 6', adapted to hook over and' rest upon the opposite sides of the tank 3. rl`he receiving vessel 6 is left open at the bottom 7 and is provided with an overow trough 3 leading from the upper portion thereof out over an end wall of the tank 3, where it may lead into a pipe 9 connected with the sewer for carrying away the overflow. ABy this arrangement, the rinsing water iiowing downwardly from can l will flow lirst within the receiving vessel 6 and will not mix at once with the contents of the tank 3, unless the level of water in the tank 3 is lower than the level or the overliow 3., llt the level ol water in the tank 3 is lower than the overflow 3, the rinsing water will run out through the open bottom of' vessel 6 until the level et liquid in tank 3 rises to the level of overflow 3, whereupon any excess ot rinsing water will flow out through said overflow without weakening the washing solution ordinarily contained in tank 3. rlhe specific i'orm` and arrangement of parts is a simple and eli'ecn tive one for the purpose.

l/Vhile l have illustrated and described the preferred formv of construction ior carrying my invention into effect, this is capable of variation and modication without departing from the spirit of the invention. l, therefore, do not wish to be limited to the precise details of the construction set forth, but desire to availmyself of such variations and modifications as come within the scope of the appended claims.

Having described my invention, what li' claim as new and desired to secure by Letters Patent, is: i

l. lin a washing machine, a tank, washing means arranged adjacent said tank, draining thereinto, a receiving vessel arranged within said tank to receive the liuid draining from said washing means, said vessel being in open communication with said tank, and an overow for said' receiving vessel leading out ot said tank, substantially 'as described.

2. lln a washing and rinsing machine, a wash water tank, rinsing means disposed above said tank and draining thereinto, a receiving vessel arranged within said tank to receive the rinsing uiddraini'ng from said rinsing means, said receiving vessel being in open communication with said tank, and an overflow for said yreceiving vessel leading out of said tank, substantially as de` scribed.

3. A device as set forth in claim 2 in which said overflow is constantly open.

4. A device as set forth in cl'im. 2 in low the level of the top of the tank, subwhich said vessel is funnel shaped and open stantially as described, at the bottom, substantially as described. In testimony whereof I have signed my 5. A device. as set forth in claim 2 in name to this specification in the presence of 5 which said vessel is further characterized 'two subscribing witnesses.

. by a supporting means engafring overthe upper edges of the sides of the tank, sub- WALTER H PAULSQN' stantially as described. Witnesses:

6. A device as set forth in c1aim'2 in JOSHUA R. H. Po'rrs,

i 10 which the overflow is arranged slightly be- LAURA J. ERICKSON.
